This invention relates to ovens for bread respective tube groups 0 and e projecting baking and similar purposes, and of the into'the space or area g above the said box, well known Perkins or closed steam tube the said area. forming part of the furnace type, and has for its object to provide imchamber containing such box. The permis- 5 proved means for varying the quantity sible extent of said movement may be such of heat supplied to different parts of the as to concentrate the heating upon either oven from its fire-box or furnace or furnaces. of the respective tube groups or to distribute The invention comprises the employment the heating over both or all the groups in with the oven, of a fire-box or furnace or any desired ratio. In the position of the' 10 furnaces in which heat is generated in any fire-box a indicated by full lines at Figure 1, convenient manner, and adapted to be varied the said box is at the limit of its movement in position relatively to the oven or to the to the right at which position the heating tubes employed for the transmission to the is concentrated, on the tube group 0.
